Going to try a few QC's over the next few weeks and see if it brings it up a bit. Overall i'm still really impressed at a 5 year old Leaf with 42k+ miles. I thought for sure I would have lost a few bars by now!

I had a 2013 with higher stats but add in the extra 1½ years of time and you are just about where I was. I bounced between 91-93% at 44,840 miles but switched to 30 kwh LEAF in Nov 2016

Nice! My 2016 SV (30kWh battery), with 14,558 miles, only has 3.86 AHr more than yours (6.6% more, even though the battery is theoretically 25% bigger and I've only got about 1/4 the miles and time you have!

“At two years of age, the mean rate of decline of SoH of 30 kWh Leafs was 9.9% per annum (95% uncertainty interval of 8.7% to 11.1%; n = 82). This was around three times the rate of decline of 24 kWh Leafs which at two years averaged 3.1% per annum (95% uncertainty interval of 2.9% to 3.3%; n = 201).”

Or, in very simplified terms, the 30-kWh LEAF seemed to have much higher battery degradation rates than the 24-kWh LEAFs.

The study concluded by suggesting that the rate of decline in the 24-kWh version of the LEAF is acceptable, but suggests that the 30-kWh pack declines too rapidly to be considered within normal parameters.Replacement Batteries – Nissan Introduces $2,850 Refabricated Batteries For LEAF

Following the release of the results of this study and our coverage of the potential issue, Green Car Reports reached out to Nissan for comment. EV communication manager, Jeff Wandell, offered this response:

“Nissan is aware that a limited number of customers have expressed concerns with the previous generation of the Nissan LEAF 30-kWh battery.”

“LEAF owners are some of our most devoted customers.”

“We take their concerns seriously, and have technical experts currently investigating the issues raised.”

We’re glad to know that Nissan is looking into this potential issue. We’ll report back if Nissan presents any additional information.

The abstract from the work titled “Accelerated Reported Battery Capacity Loss in 30 kWh Variants of the Nissan Leaf” contains more details on the issue. It states:

Analysis of 1382 measures of battery State of Health (SoH) from 283 Nissan Leafs (“Leaf/s”), manufactured between 2011 and 2017, has detected a faster rate of decline in this measure of energy-holding capacity for 30 kWh variants.

At two years of age, the mean rate of decline of SoH of 30 kWh Leafs was 9.9% per annum (95% uncertainty interval of 8.7% to 11.1%; n = 82). This was around three times the rate of decline of 24 kWh Leafs which at two years averaged 3.1% per annum (95% uncertainty interval of 2.9% to 3.3%; n = 201).

For both variants there was evidence for an increasing rate of decline as they aged, although this was much more pronounced in the 30 kWh Leafs. Higher use of rapid DC charging was associated with a small decrease in SoH. Additionally, while 24 kWh cars with greater distances travelled showed a higher SoH, in 30 kWh cars there was a reduction in SoH observed in cars that had travelled further.

The 30 kWh Leafs sourced from United Kingdom showed slower initial decline than those from Japan, but the rate of decline was similar at two years of age.

Improvements in the battery health diagnostics, continuous monitoring of battery temperatures and state of charge, and verification of a fundamental model of battery health are needed before causes and remedies for the observed decline can be pinpointed.

If the high rate of decline in battery capacity that we observed in the first 2.3 years of a 30 kWh Leaf’s lifetime were to continue, the financial and environmental benefits of this model may be significantly eroded. Despite 30 kWh Leafs accounting for only 14% of all light battery electric vehicles registered for use on New Zealand roads at the end of February 2018, there is also the potential for the relatively poor performance of this specific model to undermine electric vehicle uptake more generally unless remedies can be found.

I am now down to 8 battery bars as of this morning:2012 SL65.64% SOH40.06 ah43.49% HX45,670 miles2635 L1/L20 L3

I'm expecting to be told to pound sand, but I will call the Nissan Leaf customer line today to see if they will offer any 3/4 or 1/2 off replacement battery cost, as I am 6.5 months past battery warranty expiration.Charging behavior: I have a charge timer set to charge to 100% and have it complete roughly 30 minutes before my morning commute.

Pulled the trigger on going EV on 10/2016 with a 2012 Leaf, and a Tesla Model 3 reservation expected to receive in June 2018.

Lost third battery bar 6/4/2018:2012 SL, put into service 11/8/201161000 miles (hit that number exactly when I got home 6/3, bar was gone the next morning)47.55 AH70.48% SOH50.66% HX7 L3 charges(didn't note the number of L2 charges)

a "full" charge seems to be about 14.6 kW at this time

I still enjoy my Leaf. I liked it a bit better when I had 12 bars, though!

12/2013 Leaf 24kW (I think is left about 15kW usable)321 500kms (199 770mi)9 bars ( 2 weeks ago was 10 bars)100% to 20% in town about 85kmsQC is limited (not temp related) after 50% and up, 5% to 50% is ok speed, after that is tooo slow, imo.We have 85A/400V QC and 120A/400V in Estonia.
